Hi Noobie, I'm using a Custom Action now to set special folder permissions and a few other smaller tweaks during install. I just wasn't sure if one of the standard vsdrfXXX values would do what I want with a EXE COM server (they're poorly documented). Worst of all I have no idea how to set the custom permissions on a 32-bit COM server, although it's probably a fragile registry change which I would have to ensure works correctly on different Windows.
I've been meaning to study Wix, but time defeats me. I didn't know there was a VS2010 extension, so that's good news worth looking at. Greg
